PURPOSE:To contrive to reduce the installation area and to enhance reliability of a split type transformer by a method wherein connecting leads are led out through insulating spacers equipped to a unit transformer on one side, and are connected to gas insulated bus-bars arranged in parallel with the side in the lengthwise direction of a tank. CONSTITUTION:The connecting leads 14, 15 of the split type transformer connect the unit transformers 5A, 5B, and are connected to the gas insulated bus-bars 31, 32. At this time, the connecting leads 14, 15 are led out through the insulating spacers 35, 36 equipped to the side of the unit transformer 5A on one side, and are connected to the gas insulated bus-bars 31, 32. Thereupon, because no bushing is needed, and the distances of connecting ducts are shortened, the installation area can be reduced. Moreover, because the connecting distance to an arrester is also shortened, reliability is also enhanced. Moreover, because the weight is lightened, the earthquake-proof performance is also enhanced. |
